Abstract

The invention relates to the technical field of lighting equipment, in particular to a double-circle rotary focusing ceiling lamp capable of being limited by a check ring. The ceiling lamp comprises a shell, a light source, a radiator, a front cover and a convex lens, wherein the light source is fixed to the radiator and located in the shell, the shell is fixed to the radiator, the convex lens is fixed to the front cover, the front cover is connected with the shell, and the front cover and the shell constitute a double-circle rotary focusing mechanism. By means of the structure, the front cover is designed into the double-circle rotary focusing mechanism, and accuracy is high; in zooming, shaking of the convex lens installed on the front cover is reduced, the convex lens smoothly moves, light spot deviation is avoided, and the ceiling lamp is simple in structure, convenient to use and practical.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a double-circle rotating focusing ceiling lamp limited by a stop ring. Background technique [0002] Under the background of rising global energy shortage concerns, saving energy is an important issue we will face in the future. In the field of lighting, the application of LED light-emitting products is attracting the attention of the world. As a new type of green light source, LED It must be the trend of future development, and the 21st century will enter the era of new lighting sources represented by LEDs. LED is known as a green light source, which has the characteristics of energy saving, environmental protection, long life, small size, etc., and can be widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes and other fields. [0003] Zoom LED lamps belong to optical zoom equipment, which requires high precisi...
